'Arrows' in the Bible

For behold, I will raise and cause to come up against Babylon, an assemblage of great nations from the north country; and they shall set themselves in array against her: from thence shall she be taken. Their arrows shall be as those of a mighty expert man: none shall return empty.

Put yourselves in array against Babylon round about, all ye that bend the bow; shoot at her, spare no arrows: for she hath sinned against Jehovah.

Sharpen the arrows; take the shields. Jehovah hath stirred up the spirit of the kings of the Medes; for his purpose is against Babylon, to destroy it; for this is the vengeance of Jehovah, the vengeance of his temple.
